Can Single DMA channel be used for multiple DMA Streams

Can Single DMA channel be used for multiple DMA Streams?

As per Table 43. DMA1 request mapping in reference manual, Can I use Channel 6 for Stream0 (TIM5_CH3), Stream 3(TIM5_CH4), Stream 4 (TIM5_CH2).

I understand that Single stream I cannot use more than one channel. But how about using same channel with multiple streams? Is it ok?

Also, kindly note that I would be using all three streams simultaneously.

Yes.

In context of the 'F4 DMA, "Channel" means only the request multiplexer setting. ST chose to use a confusing terminology here.
